Budget Build Forge

AI GENERATED · EVERY STARTING FIGURE NAMES ITS SOURCE

Every budget line starts at the real 2024 figure from The US Budget Machine, and you pick how each one should go from there, then save it and run it in the Budget Build Projector.

How to use this page — step by step

Pick how each line goes

  • Every tax and every kind of spending is one budget line, showing its real 2024 amount and where that figure came from.
  • Pick one option for each line: grow with the economy, stay frozen at the 2024 amount, go up 10 percent, or go down 10 percent.
  • Pick "Your own numbers" to type your own yearly amount in billions of dollars and how fast it should grow each year.
  • Click a line's name to read its own US Budget Machine page, which explains what it is and who gains and loses when it moves.

Set the economy

  • Pick how fast the economy grows each year and what interest rate the government pays on its debt. Both are assumptions you choose, not forecasts.
  • Interest is not a line you pick, because it is worked out every quarter from the debt and the rate you chose.

Save and run it

  • The first-year box at the bottom updates as you pick, so you can see the money in, money out, interest and shortfall straight away.
  • Name the budget and press Save this budget. It is kept in this browser only, so press Copy a link to this budget to keep it anywhere or send it to someone.
  • Press Run it in the Budget Build Projector to see it quarter by quarter for up to ten years.
